Is it possible to be successful without knowing a lot of things in life?

Although the previous answer is relevant and effective, if we need a more foolproof explanation, it could sound like this:

The only difference between a winner at a situation and the less worthy counterpart is the lack of ‘knowledge’ about how to solve the problem.

Primordially, knowledge is the key to ascension following a feeling of success, but the term ‘knowledge’ is less well-understood.

Knowledge, as we commonly understand, is a collection of other people’s conclusions that we come across while reading books or understanding examples. Knowledge actually comprises of, and better defined as, a set of personal conclusions through situations faced by oneself of a higher percentage and lesser that of others’, if we want to attribute ‘knowledge’ towards bringing the sentiment of having achieved success.

A real and more practical way of becoming successful the fastest is to go through as many situations as possible in as less time as feasible.
